摘要
基于XiLinx的FPGA芯片,构建一个嵌入式的片上DPSK解调系统,对DPSK的数字化解调技术进行研究。设计中充分利用软件设计的灵活性和FPGA的可重配置特性,可根据不同的需求更改软件和硬件接口设计,以完成不同的任务。与分离设备相比,扩大了应用范围,提高了可扩充性和可兼容性,且设备集中,更易于管理和维护。
Recently,the development of aerospace TT&C have a request for a uniform equipment which includes telecontrol,telemetry and telemeter etc,it can finish multifunctional and multilist telecontrol task.For example,in a definite noise environment,telemetry de- modulation system can realize demodulation with different mode and parameters according to different task demand.The traditional method is to design an all-inclusive software and hardware platform,so the system is large and difficult to maintain and extend.In this paper,we bring forward an embedded DPSK demodulation system based on XILINX FPGA.It takes full advantage of the agility of software and the configuration of FPGA.So the system is very flexible and easy to maintain and extend.
